Battle of Penzberg

The Battle of Penzberg (late March 1805) was a battle of the Third Coalition that occurred when Emperor Napoleon and a French army of 2,148 troops decisively defeated Mikhail Kutuzov's smaller Russian army of 654 troops at Penzberg in southern Bavaria. This battle destroyed the Russian army in Germany, forcing the Russians to build new invasion armies back in Eastern Europe.

Background
At the start of 1805, the United Kingdom allied with the Austrian Empire and the Russian Empire, along with several smaller states, against the First French Empire of Napoleon I. This "Third Coalition" surrounded France, and Napoleon mobilized the people of France to fight against this coalition as a part of his Grande Armee. Austrian armies amassed in Bavaria and Italy, while Russian forces under Mikhail Kutuzov marched to their aid.
